1035.33156649 meters high is the helicopter flying over the building.
Given that, an observer (O) is located 900 feet from a building (B). The observer notices a helicopter (H) flying at a 49° angle of elevation.
We need to find how high is the helicopter flying over the building.
<h3>How to find the height of the building using trigonometry?</h3>
To measure the heights and distances of different objects, we use trigonometric ratios.
Here, use the Tangent rule to calculate the height of the building.
tan(angle) = opposite/adjacent
Now, tan 49°=h/900
⇒h=1035.33156649 meters
Therefore, 1035.33156649 meters high is the helicopter flying over the building.

Part a:-
7.15 rands = 1 dollar
So we are going to MULTIPLY to find out how many rands there are going to be.
1000 × 7.15 = <span>7150
<span>So, 7150 rands is your answer.
Part b:-
To do this first we will DIVIDE.
6274 </span></span>÷ 7.15 ≈ <span>877.482.......
So, 6274 rands is ABOUT $878.
Par a:- 7150 rands
Part b:- about $878.
